Re: LS Swap: Introduction, newbie, planning...

Read Gregski's thread on PCM programming.

Bought HP Tuners and love it. Wish I would have done it his way rather than sending my PCM out to someone.

Also, read LT1Swap.com for wiring info.

Even if you plan on using a premade harness, it's good reading to know for your swap.
